Tier-3 frontend DRY for the ML settings cards, plus the F-D2 clamp bug and the
F-D3 card misgrouping.
New primitives (components/common + composables):
- <SettingToggleRow> — the accent-icon + .fc-section-h label + right-aligned
switch row (HeadsCard x3, CropProposersCard). iconColor prop absorbs the
on/off dim.
- <SettingNumberField> — compact numeric field that CLAMPS to [min,max] on
commit. This fixes F-D2: HeadsCard/CropProposersCard previously sent
Number(raw) straight to the API, so an out-of-range threshold bounced off the
400 validator (only TranslationCard clamped). density prop for the grid cards.
- useSettingSave(patchFn) — the busy + patch + toast + revert-on-failure flow
each card hand-rolled (HeadsCard x6 handlers, CropProposersCard, MLBackfillCard,
VideoEmbeddingCard). Returns ok/false for the optimistic-switch revert.
Adopted in HeadsCard, CropProposersCard, MLBackfillCard (handler only — its
plain labelled switch is a different affordance), VideoEmbeddingCard.
F-D3: MLThresholdSliders.vue actually rendered a "Video embedding" (frame-
sampling) card but sat under "Tagging → Suggestion thresholds". Renamed it
VideoEmbeddingCard.vue and moved it to the "GPU agent & embeddings" section.
Left deliberately (over-DRY guard): TranslationCard uses an inline error ALERT
(not a toast), already clamps its confidence with a NaN fallback, and lives on
the ImportStore — a genuinely different save pattern, so forcing it onto
useSettingSave would change its UX.
Behaviour-preserving refactor; CI has no Vue type-check so this needs a live
UI pass (toggles persist + revert on failure, thresholds clamp on blur, video
card now under Embeddings).
